Need help

1. Ms. Johnson wants all the circus employees to have miniature cakes in the shape of either a circus ball or a clown hat. She wants the clown hat dessert and the circus ball dessert to have equal volumes. The radius of both cake pieces will be 3 in. What must the height of the clown hat cake be for the two cakes to be equal in volume? Round to the nearest hundredth if necessary. Explain or show your work.

..Ok......
Volume she wants should be same for both cake pieces.
Now see volume of a sphere which is a circus ball=4/3πr³

And volume of a cone is 1/3πr²h
if both are equal
4/3πr³=1/3πr²h
after simplify this
4r=h
4(3)=h
h=12 inches
